Lubricate the spigot on the *Front Gland Guide Rod tool and then place the Front Seal Gland 15, Rod Seal 25
end first, fully over spigot. Insert *Front Gland Guide Rod into the rear of the Body 2 and then push the Front
Seal Gland fully into the bore within the Body. Reasonable force is required to insert Front Seal Gland into the
Body, so the use of a press or vice may be necessary. Remove the *Front Gland Guide Rod while ensuring that
the Front Seal Gland stays in place.
